Kinks in wiring cause electrical resistance within the wire, which creates heat and could cause an electrical fire. Arcing can lead to a fire and occurs in electrical panels and enclosures, frayed wires and extension cords, and even in damaged phone chargers.

How do electrical fires start in homes?

Most electrical fires are caused by faulty electrical outlets (Receptacles) or worn out sockets that are not properly grounded. As outlets and switches get older, the wiring behind them wears as well, and wires are strung about that loosen overtime and could potentially break and cause a fire.
